A judge will consider blocking the FBI from assembling a list of agents involved in cases related to the Jan. 6 attack for potential disciplinary action or firings.

A top Justice Department official on Wednesday told FBI agents they would not be fired if they worked on January 6 investigations because they were ordered to do so and accused FBI leaders of insubordination for initially opposing demands for agents' names.

FBI officials have complied with demands to provide the Justice Department with details of thousands of employees who worked on investigations related to the January 6, 2021, US Capitol riot, according to people familiar with the situation.
